This species has a broad diet including seeds, berries, fruit, nuts and flowers. It has been observed raiding crops of maize and rice, and may also take green plant material (4). This bird tends to roost and feed in groups (2). All cockatoos develop very strong pair bonds, and the yellow-crested cockatoo is no exception. Precise details of breeding are not known for this species, the nest is usually built in a tree-hollow, and up to three eggs can be laid. Nests have also been made in burrows in cliff faces (4). In captivity both parents feed the chick, which hatches after about 27 days of incubation (2).
